It's below the opening price which is not a big deal. FB on the other hand quickly dipped below the offering price. If the 3 days expected value of a recent IPO is significantly different from the opening price, that would create an easy arbitrage opportunity.
yeah but it isn't as headline worthy. There is a syndicate of investment banks legally propping up the price at $17 for a short time. If selling pressure somehow breaches the syndicate bid, HOUSTON WE HAVE A PROBLEM.
